Abstract

The object of the present invention is to shorten the dimension in the axial direction to achieve compactness. The present invention has a movable element integrally provided with a magnet portion, weight portions, and shafts; a frame accommodating the movable element and enabling reciprocating motion thereof along a axial direction; a coil secured to the frame and drives the magnet portion along the axial direction; and elastic members exerting, on the movable element, elastic forces repelling the driving forces that act on the magnet portion. The shafts each extend toward a side along the axial direction. Tip ends of the shafts are configured as free ends. Bearings slidably supporting the shafts are secured to the frame. The weight portions have recessed portions that are formed along the axial direction. The shafts and the bearings are disposed in the spaces within the recessed portions.
